SAFETY- HOOK;

Application filed March 30, 1915. Serial No. 18,093.

To all wiiomitmay concern:

Be it known that I, FREDERICK E. Go'r- TRELL, acitizen of the United States, resid I ing at Pepper-wood, in the county of Humboldt and State of California, have invented new and useful Improvements in Safety I-looks, of which the following is a specification.

My present invention pertains to hooks for swingletrees and the like; and it consists in the simple, durable and reliable safety hook hereinafter described and definitely claimed. 2

In the drawings, accompanying and forming part of this specification: Figure l is a plan view showing my novel hook in use. Fig. 2 is a rear elevation of the same. Flg. 3 is an elevation of the outer end of the hook. Fig. 4 ma plan of the blank-from which the body of the device is preferably, though not necessarily, formed.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

On the end portion of the swingletree 1 is suitably fixed the body 2 which is provided with the hook 3; the said body being formed from the blank shown in Fig. .4, and the opposed layers of the hook 3 being connected by rivets 4:. A trace is designed to rest on the hook 3 and in the space between the hook and the outer end of the body 2, and for the purpose of guarding the mouth of the hook and precluding casual disconnection of the trace, I provide the retaining pin 7. The said pin 7 is movable endwise and also about its axis, and is provided at 8 with a laterally-disposed weight portion.

As best shown in Figs. 1 and 2, thepin 7 is arranged and movable in guides 5 and 6, and the lateral weight portion 8 is disposed and movable between the said guides. The guide 5 is arranged at right angles to the line of movement of the pin 7, and the guide 6 is arranged obliquely to said line for an important purpose hereinafter set forth. Preferably, though not necessarily, the guides 5 and 6 are formed by staples; the said staples being driven through apertures in the body 2 and into the swingletree 1 so as to serve the additional purpose of securing the body 2 on the swingletree.

It will be manifest from the foregoing that when the pin 7 is positioned as shown in Figs. 1 and 2, the weight portion 8 will tend to rest in the pendent position shown, and

will bear against the part of the guide 6 nearest the outer end of the body 2. In consequence of this the pin 7 will be effectually held 7 against endwise movement inwardly on the body 2, with the result that there is no liability of the mouth of the hook being left unguarded, and no liability of the trace becoming accidentally disconnected from the hook. When, however, it is desired for the mouth of the hook to be opened, as when a trace is being placed on or removed from the hook, the same is accomplished by the operator rocking the pin 7 about its axis,

until the weight portion 8 is in or above the horizontal, and then moving the pin 7 end-.

wise inwardly relative to the body. "When the weight portion 8 is positioned as stated Specification of Letters Patent. Patented Jan.18, 1916.

itwill be manifest that a considerable inward endwise movement of the pin 7 may be effected without interference from; the guide 6, and this notwithstanding that when the weight portion 8 is arranged as shown relative to the guide 6 the said cooperating parts will effectually prevent accidental inward movement of the pin. 4

The construction herein illustrated and described constitutes the best practical embodiment of my invention that I have as yet devised. I do not desire, however, to be understood as confining myself to the specific construction and relative arrangement of parts inasmuch as in the future practice of the invention such changes or modifications may be made as fairly fall within the scope of my appended claims.

Having described my invention, what I claim and desire to secure by Letters Patent 1s:

1. vIn means for the purpose described, the combination of a swingletree, a body mounted on the end portion thereof and having a hook spaced from its outer end, staples driven through the body and into the swingletree; the said staples constituting fastening devices and guides, and the staple nearest the outer end of thebody being disposed 1 at right angles thereto and the other staple being disposed obliquely to the body, and a pin for guarding the mouth of the hook, said pin being movable endwise and about its axis in the guides and being provided with a laterally-disposed weight portion arranged between the guides.

2. The combination of a swingletree, a'

body carried by the swingletree and having a hook the mouth of which is beyond the 2 I I I 1,1 8,482

end of the swingletree, a staple, driven Weight portion arranged between the staple through the body and into the swin'gletree and the guiding means.
